Here is my deluxe Hobbyking propulsion system , the KDA22-15M motor and a 25 amp ESC. Net total cost is maybe $30 and shipping is fast and cheap , $4-$10 range. I had a question or two: First, does that canopy retention work ? Second, the V tail retention does not look "robust" I was thinking of making a small 120 degree aluminum spreader plate [a V shaped washer basically] to go under the screw. That and I think you added canopy glue between the V tail and fuselage ? My motor mount was done as follows: filed the aluminum motor mount slightly to fit inside nose. Drilled and tapped the fiberglass mount 4-40 4X, cut out the fiberglass to clear the motor, CA'd the fiberglass to fuse with aluminum motor plate acting as a spacer, mixed JB weld and applied to reverse side of fiberglas ring, installed 4-40 cap screws with 1/8" of threads running into the JB weld before it hardened. I am going to permanently solder the ESC to the motor and use an extension to reach the receiver.
